Sorry for jumping in.
Finally, I found this thread.


My environment is completely different (ARM64 board),
I am also suffering from a hibernation problem
since this commit.


I get no response on the serial console
after "Restarting tasks ... done." log message.


By reverting bf22ff45bed6 ("genirq: Avoid unnecessary low level
irq function calls", I can get hibernation working again.


SW info:
defconfig:  arch/arm64/configs/defconfig
DT       :  arch/arm64/boot/dts/socionext/uniphier-ld20-ref.dts
PSCI     :  ARM Trusted Firmware


SoC info:
CPU      :  Cortex-A72 * 2 + Cortex-A53 * 2
irqchip  :  GICv3 (drivers/irq/irq-gic-v3.c)
